Sheboygan County Fair Parks' Plymouth Dirt Track, Saturday the 21st

This coming Saturday night's (July 21) Bumper To Bumper IRA Outlaw Sprint Series headlined event at the Sheboygan County Fair Parks' Plymouth Dirt Track is a important one for several reasons. Additional $ is being added to the purse in all 3 competing classes courtesy of the Fenske Family in memory and honor of their beloved Roy Fenske. Roy was an avid race fan, attended the Plymouth Dirt Track weekly, and proudly operated Roy's Christmas Trees locally for many years. The event is also Round 2 of IRA's Hopf Farms Bullring Showdown, series within a series. And the night also has lots of history and prestige as it's the 22nd annual Frank Filskov Memorial, paying tribute to the popular IRA sprint racer.
Joining the IRA winged 410's will be the PDTR/MSA winged 360 Sprints, and PDTR Sport Mods. All three classes will have money added to their purse courtesy of the Fenske Family. Due to schedule changes and rainouts, Dean & Stacy Hopf have been forced to change a few Bullring Showdown dates, so this Saturday at Plymouth will be followed by the Labor Day weekend combo, the Saturday Sheboygan County Fair date, and then the very next night at 141 Speedway on Sept 2. The Bullring finale is now currently scheduled Sept 22nd at Beaver Dam Raceway, with a raindate of Sept 29, at their home track in Plymouth.
